Steven Willis commented on OOZIE-986:
-------------------------------------
I did see the JAVA_PROPERTIES, but there are two issues I have with that. I
can't currently use it since the oozie script provided by
oozie-3.1.3-incubating-distro.tar.gz overwrites JAVA_PROPERTIES to the empty
string before its use. Though it looks like this was fixed in [commit
2a1026|https://github.com/apache/oozie/commit/2a102670c38636dc652b4089a33829bd739ff64c#client-src-main-bin-oozie-P0].
Second issue is just consistency with other scripts.
The specific use case I'm having is that I actually want to lower the heap
space used as one of the systems I'm running under will kill a process if it
uses over 1GB of memory, which it seems like java does if I don't use "-Xmx".

> All the hadoop shell scripts (hadoop, hdfs, mapred, yarn) allow the setting
> of HADOOP_CLIENT_OPTS to pass custom options to java. I think the oozie shell
> script should allow the same through OOZIE_CLIENT_OPTS and similarly respect
> JAVA_HEAP_MAX like the hadoop shell scripts.
